We introduce an alternative thermal diffusive dynamics for the spin-S Ising ferromagnet realized by means of a random walker. The latter hops across the sites of the lattice and flips the relevant spins according to a probability depending on both the local magnetic arrangement and the temperature. The random walker,…
We introduce a diffusion model for energetically inhomogeneous systems. A random walker moves on a spin-S Ising configuration, which generates the energy landscape on the lattice through the nearest-neighbors interaction. The underlying energetic environment is also made dynamic by properly coupling the walker with th…
ZnO nanorods with hexagonal structures were synthesized by a hydrothermal method under different conditions. The effect of synthesis conditions on ZnO nanorod growth was systematically studied by scanning electron microscopy. All samples were characterized by X-ray diffraction, energy-dispersive X-ray spectroscopy and…
We report on the development and the performance of a new instrument for soft X-ray scattering experiments. A ultrahigh- vacuum-compatible two-circle diffractometer was realized by mounting two differentially pumped rotary platforms on top of a cylindrical vacuum chamber. The concentric rotations of the detector and s…
Thin carbon nanofibers with less than 100 nm diameter were variously prepared over MgO-supported nickel and bimetallic nickel catalysts with iron, copper, and molybdenum. The second metal effects on the carbon yield and structure were investigated by using electron microscopic and gas chromatographic methods. Further,…
In this study, we report the cloning and characteristics of an adiponectin-like receptor gene from Bombyx mori (BmAdipoR) with highly conserved deduced amino-acid sequences and similar structure to the human adiponectin receptor (AdipoR). Structural analysis of the translated cDNA suggested it encoded a membrane prote…
A Sieverts' apparatus coupled with a residual gas analysis is used to measure the concentration variations of hydrogen isotopes in the gas and solid phases during exchange and isothermal decomposition of mixed hydrides. beta-phase palladium hydrides with known ratios of H:D, Pd(H x D 1- x ) y (0 < x < 1, y > 0.6), are…
Abstract Miniaturization of nanofibers formed from melamine-appended perylene bisimides and cyanurates are achieved by elongating the linker moieties between perylene bisimide core and melamine moieties. The resulting nanofibers gelate aliphatic solvents with low concentrations and the resulting gels are optically tra…

Abstract Using a sol–gel/spin-coating method, transparent mesoporous silica thin films containing single-site photocatalyst (Ti, V, Cr, Mo, and W oxide moieties) (Me-MSTFs) could be prepared on quartz plates. All Me-MSTFs have exhibited strong hydrophilic surface properties even before UV-light irradiation and showed…
An atomistic model of imogolite was defined and tested in molecular dynamics simulations. The model is based on the structure by Cradwick et al. ( Nature, Phys. Sci. 1972, 240, 187). The interatomic interactions were defined by a generalized valence force field. As the experimental samples are mostly hydrated, water m…
A new BC 3.3 N crystalline compound with orthorhombic structure has been synthesized using an amorphous B−C−N precursor at 6 GPa and 1773 K. Results of energy-dispersive spectroscopy (EDS) and electron energy loss spectroscopy (EELS) experiments show that the compound has a 1.04:3.27:1 B:C:N chemical stoichiometry. Th…
This study is the first one using the Taguchi experimental design to identify the optimal operating condition for reducing polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/ Fs) formations during the iron ore sintering process. Four operating parameters, including the water content (Wc; range = 6.0-7.0 wt %),…
Four novel fluoro-functionalized arylimido-substituted hexamolybadates, ( n -Bu 4 N) 2 [Mo 6 O 18 (NAr)] (Ar = 2-CH 3 -4-FC 6 H 3 ( 1 ), 3-CH 3 -4-FC 6 H 3 ( 2 ), 4-FC 6 H 4 ( 3 ), or 2-FC 6 H 4 ( 4 )), in which fluorinated phenylimido group linked to an Mo of hexamolybdate by a Mo−N triple bond, have been prepared vi…
Abstract We have prepared spin-crossover [FeL2(NCS)2] complexes chelated with alkylated N-(di-2-pyridylmethylene)anilines. The wider irreversible thermal loop across room temperature was observed with the longer alkyl chain introduced (ΔTC = ca. 90 K for a n-C16H33 derivative). Pressurization prohibits the solid–solid…
A systematic survey is presented of the maximum packing fractions obtained by decorating the 28 uniform tilings of three-dimensional space with spheres of one size and then filling the interstices of these tilings, starting with the largest, with spheres of different sizes. A number of size ratios and structures are i…
In thin films of porphyrin (H 2 P) and gold nanoparticles (AuNPs), photoexcitation of porphyrins leads to energy and charge transfer to the gold nanoparticles. Alternating layers of porphyrins and octanethiol protected gold nanoparticles ( d core ∼3 nm) were deposited on solid substrates via the Langmuir−Schäfer metho…
The nanoscale positioning of QD donors and dye acceptors enables an effective control of the fluorescence resonance energy transfer from QDs to dyes in a single-layered film of diblock copolymer micelles.
The synthesis and colloidal study of a new class of low molecular weight organogelators is reported. Racemic propargylic alcohols with perfluoroaryl and nonfluorinated aryl rings are capable of forming gels in alkane liquids and/or silicone oil. A full colloidal characterization of alkane gels prepared from (R/S)-1-pe…
